Bistatic backscatter
WebFirstly, we have introduced the fundamentals of modulated backscatter and its three main configurations, i.e., monostatic, bistatic, and ambient backscatter communication systems. Then, key channel-coding and modulation techniques in modulated backscatter communication systems are discussed. Web15.1.11 Sound backscatter. Backscatter is the reflected sound from any object being insonified—the analysis of which is the subject of active sonar systems. Backscatter is …

Abstract: For applications that require large numbers of wireless sensors spread in a field, … WebDec 3, 2024 · Bistatic backscatter communication is emerged as a promising technique to significantly enlarge the lifetime of internet of things (IoT) network due to its inherently low-power passive component.
WebNov 5, 2012 · This work examines the idea of dislocating the carrier transmission from the tag-modulated carrier reception, i.e. bi-static rather than mono-static backscatter radio. In that way, more than one ... WebNov 11, 2024 · Abstract: Bistatic backscatter communication (BackCom) allows passive tags to transmit over extended ranges, but at the cost of having carrier emitters either transmitting at high powers or being deployed very close to tags.
WebAug 30, 2010 · Measurements were performed at 5.8 GHz and estimates of the backscatter channel envelope distributions and fade margins were calculated. Results show that multipath fading can be reduced using multiple transponder antennas, bistatic interrogators with widely separated transmitter and receiver antennas, and conventional diversity …
WebSep 15, 2024 · THz Bistatic Backscatter Side-Channel Sensing at a Distance Abstract: This article presents the sensing and detection of backscattered terahertz (THz) side channels unintentionally created by field-programmable gate array (FPGA) activity using a bistatic arrangement.
WebAlso, there are high hopes that the bistatic radar capable of observing the electromagnetic wave scattered from the target in other directions than back to the transmitter would be able to detect stealth objects that by design should be undetectable by the monostatic radars.
